One thing I find annoying with my sony z1 compared to an iphone 5 is how the camera just dies half of the time whenever I try to take a picture from a locked phone. In iOS it's never a problem. Lets hope amazon doesn't screw it up with their phone. Another annoying thing is how it refocuses between each photo, decreasing burst speed.
